Therefore, smart grids can have multiple shapes because there is no single unified concept of what constitutes a ＂Smart Grid＂. Smart grid is considered a core concept in sustainable electricity generation and consumption while being projected as a silver-bullet to electric power system challenges. South Africa＇s dwindling reserve margin, high CO_2 emissions and future energy mix are outstanding reasons for her smart grid deployment. Who receives the credit for smart grid neology is contentious and smart grid definition is diverse. However, there is a consensus on its attributes or benefits. The establishment of SASGI （South Africa Smart Grid Initiative） and Eskom＇s commencement of deploying a hybrid smart grid model are proofs of the country＇s commitment towards smart grid concept and developments. Having recognized the relevance of smart grid concept and its developments, South Africa is presented with the opportunity to ＂leap-frog＂ and enhance the relevant proven applicable smart grid solutions.展开更多

We propose the front-face detection from four captured images related to the intelligent room for the deaf. Our proposal purpose is that a deaf user faces wall displaying everywhere. system gets the images from four cameras, and detects the user region from a silhouette image using a different method, detects and cuts a motion body region from a different image, and cuts the vertexchest region from the cut body region image. The system attempts to find front-face using Haar-like feature, and selects a detected front-face image from the vertex-chest region. We estimate the front-face detection of recognition rate, which shows somewhat successfully.展开更多
